NSK 1 Row Steel Ball Thrust Bearing 45 mm Inside Diameter 65 mm Outside Diameter 14 mm Race Width Model 51109

NSK 51109 is a 1 Row Steel Ball Thrust Bearing designed to handle unidirectional axial loads in a variety of industrial settings. This bearing features a precise 45 mm inside diameter and a 65 mm outside diameter, complemented by a 14 mm race width. Constructed entirely of steel, including cage and balls, the bearing assures durability, strength, and longevity.

Belonging to the 1 Extra Light Thrust series, the NSK 51109 bearing type is a thrust ball bearing optimized for applications requiring axial load support without radial load. It incorporates a parallel bore type with CN internal clearance providing accurate alignment and smooth rotation at limiting speeds up to 5000 rpm.

This bearing is engineered with a static load rating of 69 kN and a dynamic load rating of 28.1 kN, capable of handling rigorous operational loads in demanding environments. Its plain race design and steel components ensure resistance to wear and mechanical stress under continuous use.

Thrust ball bearings like the NSK 51109 are widely employed across aerospace, marine, automotive, and manufacturing industries. They are ideal for vertical shaft bearings, steering column supports, and other mechanisms requiring precise axial load management. However, it is important to avoid radial loads to prevent mechanical failures.

High-quality steel materials enhance bearing lifespan and mechanical reliability. Single-row configuration suited specifically for axial thrust loads. Compact design with 14 mm race width for space-efficient assemblies. Robust ratings ensure suitability for industrial and automotive applications.

Parallel bore and CN internal clearance provide precise operational fit. Limiting speed of 5000 rpm supports high-performance rotary tasks. Common application in gearboxes, clutches, steering systems, and marine equipment.

Not designed for radial load; misuse can cause bearing damage. Set contains 1 Pc NSK 51109 steel ball thrust bearing with all specified dimensions and ratings.
